UNISEXUAL SELECTION AT AN AUTOSOMAL LOCUS

Unisexual selection at an autosomal locus.

Mutation-selection balance under genomic imprinting at an autosomal locus.

I model the effect of genomic imprinting on the equilibrium allele frequencies at an autosomal diallelic locus subject to viability selection and mutation. The population size is assumed to be very large; male and female mutation rates may be unequal. Different models examine cases of the inactivation of one gene (with both complete and partial penetrance) and of differential expression of gene...

Sex-specific meiotic drive and selection at an imprinted locus.

We present a one-locus model that breaks two symmetries of Mendelian genetics. Whereas symmetry of transmission is breached by allowing sex-specific segregation distortion, symmetry of expression is breached by allowing genomic imprinting. Simple conditions for the existence of at least one polymorphic stable equilibrium are provided. In general, population mean fitness is not maximized at poly...

Selection at the transferrin locus in mice.

VIDENCE for an effect of the transferrin locus on some aspect of fitness has E been presented for cattle (ASHTON 1958, 1965; ASHTON and FALLON 1962), pigs (KRISTJANSSON 1964; SMITH et aE. 1968), poultry (MORTON et al. 1965), and tuna (FUJINO and KANG 1968). TAMARIN and KREBS (1969) have reported that one Tf allele is at an advantage when natural populations of Microtus are declining in numbers....

Reduced variation among northern deer tick populations at an autosomal microsatellite locus.

To determine whether genes flow freely between populations of the Ixodes ricinus-like ticks of eastern North America, and to determine whether the abundant northerly populations of these vectors of Lyme disease and other zoonotic infections may have arisen recently from a small cohort of ancestral founders, we characterized the nuclear IR27 microsatellite alleles in ticks sampled from the geogr...
